MOBILE COMMUNICATION SYSTEM
First Claim
1. A mobile communication system in which a radio base station interface between a first mobile station and a second mobile station and a radio base station and an inter-mobile station interface between the first mobile station and the second mobile station are specified,wherein the radio base station is configured to transmit a data signal to the first mobile station and the second mobile station through the radio base station interface at a first frequency,the first mobile station and the second mobile station are configured to transmit the data signal to the radio base station through the radio base station interface at a second frequency, the first mobile station and the second mobile station are configured to transmit and receive the data signal to and from each other in a time-division manner through the inter-mobile station interface at the second frequency, andpredetermined gaps are configured to be provided before and after timing in which the first mobile station and the second mobile station transmit the data signal through the inter-mobile station interface.

Abstract
Orthogonality between signals is maintained in direct communication between a mobile station UE#1 and a mobile station UE#2. In a mobile communication system according to the present invention, a radio base station eNB is configured to transmit a data signal to the UE#1 and the UE#2 through a Uu interface at a frequency f1, the UE#1 and the UE#2 are configured to transmit the data signal to the radio base station eNB through the Uu interface at a frequency F2, the UE#1 and the UE#2 are configured to transmit and receive the data signal to and from each other in a time-division manner through a Ud interface at the frequency F2, and predetermined gaps are configured to be provided before and after timing in which the UE#1 and the UE#2 transmit the data signal through the Ud interface.
